Summary

In a randomized trial of 255 participants with early-stage T2D, participants will be randomized to 1 of 3 groups: Standardized, Personalized, or a Usual Care Control (UCC). In the first phase, participants will be randomized with equal allocation to these 3 groups. In the second phase (current phase), the remaining participants will be randomized with equal allocation to the Standardized and UCC groups.

Conditions

Interventions

BEHAVIORAL

Standardized

Participants are instructed to follow a Mediterranean-style diet. Dietary counseling is paired with SCT-based behavioral counseling, which focuses on the role played by self-referent thought in the maintenance of behavior change. Self-efficacy (e.g., the participant's confidence in their ability to engage in healthier behavior) is derived from four major sources of information: mastery experiences, social modeling, verbal persuasion, and physiological states. Participants self-monitor their diet using a mobile app and receive real-time feedback from the app on macronutrient distribution.

BEHAVIORAL

Personalized Guidance to Minimize Postprandial Glycemic Response (PPGR)

Participants are instructed to follow a Mediterranean-style diet. Dietary counseling is paired with SCT-based behavioral counseling, which focuses on the role played by self-referent thought in the maintenance of behavior change. Self-efficacy (e.g., the participant's confidence in their ability to engage in healthier behavior) is derived from four major sources of information: mastery experiences, social modeling, verbal persuasion, and physiological states. Participants self-monitor their diet using a mobile app and receive real-time feedback from the app on their predicted PPGR to meals and snacks at the time they enter them into their smart phone. PPGR predictions will be generated from a gut microbiome-based machine learning algorithm.
